DESCRIPTION

The invention concerns a military motor vehicle for transporting personnel. The vehicle is comprised of a chassis on which a transport structure is mounted behind a driver's cabin. The transport structure serves to accommodate personnel and therefore contains several seats and/or benches. The top of the transport structure is open and can be covered with a tarpaulin. The top is also equipped with a roll protection device.

Military motor vehicles that can be transported in medium size aircrafts and especially in helicopters are becoming more and more important for international military operations. In order to enable transporting in such an aircraft, they have to meet certain requirements regarding weight empty and external-dimension measurements. This invention is based on the object of developing a military motor vehicle that would meet the above-mentioned requirements and that could be manually adjusted for loading into and aircraft. It is of particular importance that the vehicle's height not exceed the permissible loading dimension.

To solve this problem, the roll protection device is formed of two longitudinally extending roll bars, each placed above one of the side walls of the transport structure. Both ends of each roll bar are locked to the transport structure and can be released. Reinforcing elements running transverse to them connect the roll bars.

Advantageous developments of the invention are described below.

The total height of the military motor vehicle is mainly defined by the roll protection device on top of the transport structure. The basic idea of this invention is to develop a roll protection device that can be quickly moved from a higher work position to a lower transport position after releasing the locking devices. For this reason, the roll protection device comprises two roll bars extending in the longitudinal direction over the whole length of the transport structure. Reinforcing elements running transverse to the direction of the roll bars connect them. A releasable lock connects both ends of each roll bar with the transport structure. After releasing the lock it is therefore possible to quickly detach the entire roll protection device and place it in a lower position. A particular embodiment of the roll protection device has the advantage that the roll bars can simply be shifted from a higher work position to a lower transport position after the locking devices have been released.

For the purpose of saving weight, the backrests including neck supports of seats or benches can be integrated into the reinforcing elements that extend transverse to the roll bars. It has further turned out to be an advantage that the height of the drivers cabin can be reduced for loading and transporting purposes. This is possible because the driver's cabin has a hood that is connected to the back wall of the cabin by hinges. The hood can be shifted rearwards (at least 180°) so that it comes to rest between the side walls of the transport structure.

It is possible to load the military motor vehicle equipped according to the described invention into a helicopter, e.g. of the type CH 53.

The military motor vehicle represented in the drawings is designed for transporting personnel. It is comprised of a chassis 1, on which a driver's cabin 2 is placed in the front and a transport structure 3 for seating personnel is placed in the rear. The tarpaulin that can cover the open top of the transport structure is not shown. In the front part of the transport structure 3, two single seats 4 and 5 are located facing opposite to the direction of travel. In the middle part of the transport structure, behind the single seats 4 and 5, a bench 6 seats three persons facing in the direction of journey. In the back part of the transport structure, behind bench 6, another bench 7 seats three persons facing opposite to the direction of travel. Seats 4 and 5 have backrests, each with a horizontal axis of rotation 13.1, 13.2. This way, the upper parts 4.1 and 5.1 of seats 4 and 5 can be tilted rearwards. Benches 6 and 7 have the upper parts of their backrests 6.1 through 6.3 in common. The horizontal axis of rotation 12 allows for them to be tilted.

A roll protection device is located on top of the transport structure 3. It comprises two roll bars 8.1 and 8.2, each of them located above one of the side walls 3.1 and 3.2 and extending over the full length of the transport structure 3. The ends of each roll bar 8.1 and 8.2 are releasably connected to the transport structure 3 by locking mechanisms 8.11, 8.12, 8.21 and 8.22. The two roll bars 8.1 and 8.2 are interconnected by three reinforcing elements, running transverse to them. The first reinforcing element is located in the front part of roll bars 8.1 and 8.2. It is formed as a crossbar 9.1, which is fixedly attached to the roll bars 8.1 and 8.2 and is connected to the upper parts 4.1 and 5.1 of seats 4 and 5 by the attachment elements 4.2 and 5.2. The second reinforcing element is located on the back end of the roll bars 8.1 and 8.2, above the back wall 3.4 of the transport structure 3. It is formed as a crossbar 9.2, which is also fixedly attached to the roll bars 8.1 and 8.2.

A third reinforcing element is the crossbar 10, located between crossbars 9.1 and 9.2. It is connected to the roll bars 8.1 and 8.2 by the swivel joints 10.1 and 10.2. The crossbar 10 is attached firmly to swivel arms 11.1, 11.2 and 11.3, which can be rotated around their common pivot axis 12. In the embodiment described here this is possible because the swivel arms 11.1, 11.2 and 11.3 are integrated in the upper parts 6.1, 6.2 and 6.3 of the backrests of the benches 6 and 7. They are arranged in such a way that the swivel arms 11.1 though 11.3 together with the upper parts 6.1 through 6.3 of the backrests can be rotated around axis 12 and brought from an upright, locked position to a lower, inclined position. The axes of rotation are approximately located at halfway along the height of the transport structure 3.

On the basis of the construction described above, the roll bars 8.1 and 8.2 can be moved rearwards after releasing the locking devices 8.11, 8.12, 8.21 and 8.22. By doing this, the roll bars 8.1 and 8.2 can be shifted from a work position into a lower transport position. FIG. 6A shows the roll bars in work position, FIG. 6B illustrates an intermediate position and FIG. 6C the end position with the roll bars 8.1 and 8.2 shifted rearwards all the way. FIG. 6D shows the complete arrangement of lowered roll bars 8.1 and 8.2, all rocking arms that support roll bars 8.1 and 8.2 and the seats or parts of seats that are connected to the swivel arms. For further reinforcement, the transport structure 3 is equipped with diagonal reinforcing members. FIG. 3 shows an example of such a reinforcing element the front wall 3.3 of transport structure 3 has two diagonally running cables 14. In addition, the backrests of benches 6 and 7 and their integrated neck supports serve as reinforcing elements. None of the seats and benches is attached to the floor of the transport structure 3, and benches 6 and 7 are self-supporting. As shown in FIG. 1, cargo can be stored in the spaces 17.1 and 17.2 underneath benches 6 and 7. The design of both benches limits the cargo space underneath and prevents the cargo from shifting.

The driver's cabin 2 of the military motor vehicle has a roof 2.1 that is connected to the back wall of the driver's cabin by hinges (22). Due to these hinges, the roof can be manually shifted rearwards traveling through an angle of more than 180° and coming to rest between the side walls of the transport structure 3. This makes it possible to reduce the total height of the driver's cabin 2 to meet loading requirements. The process is shown in FIG. 6A through 6D. In FIG. 6B, the roof 2.1 of the driver's cabin is shown in a partly shifted position. A torsion-bar spring not shown facilitates the opening and closing of hood 2.1. The initial tension in the spring is adjusted in such way that the roof 2.1 is relieved at an aperture angle of approximately 90°. That means that the effort necessary to shift the hood 2.1 either way is initially facilitated by the torsion-bar spring.

FIGS. 6C and 6D illustrate that a combination of folding back the roll protection device and folding back the roof of the driver's cabin reduces the height of the military motor vehicle significantly. FIG. 7 shows that the height can be reduced to L=1,890 mm. It is then possible to load the military motor vehicle into a helicopter, e.g. type CH 53. In FIG. 7 the flight space 16 of a helicopter CH 53 is indicated schematically. The figure shows that the military motor vehicle can be loaded into the helicopter.
